EDWIN DUNBAR BANGs, on MILWAUKEE, Wisconsin LUB'RICATOR.

SPECIFICATION forming part o'f Letters Patent No. 640,079, datedDecember 26, 1899.

Application filed March 3, 1899. Serial No 707,631. (No model.)

To @ZZ whom t may concern.-

Beit known that I, EDWIN DUNBAR BANGs, of Milwaukee,in the county ofMilwaukee and State of Wisconsin, have invented a new and ImprovedLubrcator, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide a simple and economiclubricating device especially adapted for supplying lubricating materialcontinuously and regularly to the bearings or journals of locomotive andmarine engines and to employ air-pressure to effect such feed.

Another object of the invention is to provide a nozzle for theintroduction of oil into the feed-pipes or the exit of oil therefrom,which nozzle will be so constructed that any foreign matter in thelubricating material Will not tend to clog the pipes.

The invention consists in the novel con` struction and combination ofthe several parts,as Will be hereinafter fully set forth,and pointed outin the claims.

Reference is to be had to the accompanying drawings,forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the iigures.

Figure 1 is a rear elevation of a locomotivecab and a vertical sectionthrough the main frame of the engine,il1ustrating theinvention in frontelevation as applied to the boiler. Fig 2 is a plan view of a portion ofthe main frame of the locomotive, showing the manner in which alubricating material is directed to the bearings. Fig. 3 is an enlargedfront elevation of the improved device, parts thereof being in section.Fig. 4 is an enlarged View of a drip-pipe and the coupling for said pipeattaching it to the lubricating-supply pipe, a portion of the drip-pipebeing in section and likewise a portion of the coupling. Fig. 5 is aplan View of the nozzle used in connection with the inlet end of alubricating-supply pipe, and Fig. 6 is a side elevation of a nozzleadapted to be located at the delivery end of the drip-pipe.

A represents the rear end of a locomotiveboiler,and B bearings for theaXle of a truck C.

D represents the engineers valve, and D the pipe from the air-pressurereservoir leading to said valve, and D2 represents the airvent for thesaid engineers valve,all of which parts may be of ordinary construction.

- E represents a tank of any desired shape or of any suitable sizeadapted to contain lubricating material. Said tank is provided with afaucet atits lower end,whereby its contents may be removed, and the tankis further provided Wit-h a gage-glass 11 'at the front,where by thelevel of the lubricating material in the tank may be readily discerned.The lubricating material is fed into the tankE through the medium of acup 12, connected With the top portion of the tank, a suitable valve 13intervening the said cup and tank, and a petcock 14 is also located atthe upper portion of the tank to permit the escape of air When the tankis to be supplied witha lubricating material. A gage 15 is alsoconnected with the upper portion of the tank, adapted to indicate theamount of air-pressure in the tank E, the air being delivered into thetop .portion of the tank above the level of the lubricating materialthrough the medium of a pipe 16,that connects with the pipe D from theengineers valve, as shown in Fig. 1, the said air-supply pipe 16 havinga valve 17 suitably placed between its ends.

An outlet-pipe 18 is usually connected With each side of the tank E ator near its bottom. These outlet-pipes 18 are shown as of elbow shapeand are made tapering, their inner ends being of less diameter thantheir outlet ends. In connection with each outlet-pipe 18 at its outletend a nozzle 19 is employed, said nozzle being in the form of a plughaving an eX- teriorly-threaded surface, whereby it may be screwed intothe outlet portion of the outletpipe. Each nozzle 19 is tapering at itsinner end and is provided with a correspondinglytapered bore 2l,extending from the point of the nozzle to a communication with theenlarged opening 22.

Any suitable form of coupling 24 is adapted to connect the outlet end ofan outlet-pipe 18 with a lubricating-supply pipe 23, and thelubricating-supply pipe or pipes may be carrie'd over any bearing or boxthat is to be lubricated, as shown in Fig. 2. Each nozzle 19, as shownin Figs. 3 and 5, is provided with a IOO polygonal upper extension 19,through which the enlarged opening 22 is continued, and said extension19a enables the nozzle to be mani pulated by a wrench or a like tool.

Wherever a bearing or a box B is to be lubricated the supply-pipe 23 isprovided, preferably,witl1 a T-fitting 24, as shown in Figs. 2 and 4,and a drip-pipe 25 is coupled in any suitable or approved manner withone niember of a T-fitting, the delivery end of a drippipe being adaptedto extend over the oil-receiving opening of or a cup connected with thebearing or journal to be lubricated.

Each drip-pipe 25 is provided at its delivery end with a nozzle 27, andeach of said nozzles consists of an upper reduced andexteriorly-threaded section 28, the upper end whereof is conical, and abase-section 29 of greater diameter than the upper section 28, and whenthe upper section 28 is screwed into the drip-pipe the delivery end ofthe drippipe will engage with the upper edge of the lower section 29 ofthe nozzle, as shown in Fig. 4. The reduced section 28 of a nozzle 27 isprovided with a tapering bore 30, that extends from the apex of saidreduced section into the larger and lower section 29, said bore 30 beingof greatest diameter at its lower end, and said bore 30 connects with achamber 31 in the bottom of the base-section of the nozzle, whichchamber is of greater diameter or cross-sectional area than the diameteror cross-sectional area of the outer end of the tapering bore 30.

It will be observed that when nozzles are employed constructed asdescribed the conical portions of the nozzles face the direction ofsupply, and that if any foreign matter be contained in thelubricatingmaterial said foreign matter will be deflected to either side of thenozzle, leaving the bore of the nozzle free, and that if any particle ofsuch foreign matter should be able to enter the contracted end of thenozzle-bore said foreign matter will be forced through the nozzle intothe enlarged portion of the bore and from thence outward, thus insuringa continuous and regular supply of lubricating material to any bearingor journal where the nozzles at the end of the drip-pipes or otherequivalent pipes may be directed.

I desire it to be understood that any number of drip-pipes may beconnected with a supply-pipe and that each drip-pipe employed have thesame restricted outlet. Thus the amount of material dispensed by eachdrippipe is the same no matter what relation the drip-pipe may sustainto the source of supply.

Having thus described my invention, I

claim as new and desire to secure by Letters Patentl. In lubricators atapering supply-pipe, and a nozzle for the wider end of said pipe, saidnozzle being provided with a conical surface facing the inlet of thesupply-pipe, said nozzle being furthermore provided with a ta-l peringopening, the contracted end of the opening being its receiving end, saidnozzle ,having also an outlet-chamber in connection with the taperingopening, the said chamber being of greater cross-sectional area than thegreatest cross-sectional area of said tapering opening, a coupling atthe opposite end of the supply-pipe, and a distributing-pipe connectedwith the coupling, the distributing-pipe being of less diameter than thesupply-pipe and of greater diameterthan the nozzle-outlet, as described.

2. The combination, with a reservoir adapted to contain a lubricatingmaterial, and tapering outlet-pipes connected with said reservoir, ofnozzles located at the outer wider ends of said outlet-pipes, the innerends of the nozzles being conical, each nozzle being provided with astraight outlet and a tapering inlet the reduced portions whereof are atthe points of the nozzles, and distributingpipes coupled to thesupply-pipes at their nozzle ends, said distributing-pipes being ofgreater diameter than the nozzle-outlets and of less diameter than thedelivery ends of the supply-pipes, as described.

3. The combination, withareservoir adapted to contain a lubricatingmaterial, and outlet-pipes connected with said reservoir, of nozzleslocated at the outer ends of said outletpipes, the inner ends of saidnozzles being conical, each nozzle being provided with an interiorchamber extending through its outer end and with a tapering boreextending from the said chamber to the point of the conical end of thenozzle, the contracted portion of the bore being at said apex, asupply-pipe connected with the outlet-pipes at a point adjacent to thechamber in said nozzle, a series of drip-pipes connected with saidsupply-pipes and adapted to be carried over journal -boxes, and nozzleslocated at the ends of the drippipes, the inner ends of the nozzlesbeing of conical shape and said nozzles being provided with taperingbores and with outlet chambers in communication with the larger ends ofsaid tapering bores, as specified.
